Crystal this is a great pros & cons list. I agree with all of it. :)
Tom and I do still enjoy taking land based trips (that is how we met Kristin & Greg :app: ), but we do lean more towards luxury cruising when it comes down to making a choice.
Also, since land based "warm climate" trips is what my job is I need to try and keep up on all the nice resorts (such a hard job you know...checking them out and making sure my clients will enjoy staying there)! ;)
